Is my /root/.bash_profile set up properly to run a java program I have for my mp3 player?

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs
export JAVA_HOME=/opt/j2sdk_nb/j2sdk1.4.2
export PATH=$PATH:$JAVA_HOME/bin
PATH=$PATH:/opt/j2sdk_nb/j2sdk1.4.2/bin
CLASSPATH=$CLASSPATH:/opt/j2sdk_nb/j2sdk1.4.2/lib:/opt/j2sdk_nb/j2sdk1.4.2/jre/lib
export PATH CLASSPATH
PATH=$PATH:$HOME/bin
BASH_ENV=$HOME/.bashrc
USERNAME="root"

export USERNAME BASH_ENV PATH

The program sits in /

looks alright. what's the error?

neuros]# java -jar /neurosjar/NeurosDBM.1.23.jar
bash: java: command not fou

if you do
echo $PATH
in a console you should see
/opt/j2sdk_nb/j2sdk1.4.2/bin
somewhere? is this true?

]# echo $PATH
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/root/j2re1.4.2_03/bin/java/bin:/home/booda/bin

Yes. There it is.

where do you installed it? under /root/j2re1.4.2_03 or /opt/j2sdk_nb/j2sdk1.4.2? something seems to be wrong....

I installed it in /root. That was wrong ?

i would'nt install it under root. i'd do it in /opt/java or /usr/local/java, so every other user can use java too. but if you have installed it in /root, your .bash_profile is wrong:
export JAVA_HOME=/root/j2re1.4.2_03
this variable must point on your java installation

i wouldn't put it in /root... then you'd have to run as root all the time, as the /root directory is locked to non-root users.

and you know you should NOT routinely run as root... right?

I think this link will help you get java setup: http://fedora.artoo.net/faq/#Java I would uninstal your current setup of java and start over again.

thanks
